The carb on the right has an angled vent port on the bottom, carb on left does not. Is this by design? If not, are these available?
Are they actually even called this?
Thx.

on the bottom bowl? thats the over flow nipple. they both originally came with them. its part of the bowl assembly, so not sold separately as far as i know.  you can run w out them if need be .i think its 4mm dia.

If I remember correctly, on RD350 carb bowls there should be one straight tube pointing directly down on the right side, and on the left (choke side) carb there should be a forward facing tube. I can go out an double-check on my '73 if needed

i have a (large) box of stock carbs and parts, if you need one let me know i'll mail you one. it does make for a neater package running the drain tubes down the drain hole int he cases.

found one, i'll send the whole bowl, good shape just needs a cleaning, and no risk of damaging it trying to pull the fitting out.

i've been on a lot of different forums. anywhere from metal detecting to classic cars to name a few.
i can honestly say i think this forum is actually full of people who genuinely want to see the other members have success building and riding their bikes. sometimes offering parts for next to nothing or just paying shipping. it's happened to me and i am glad to be part of this forum.  :righteous:
